Bo it known that T, MnLviN C. DART, a citizen oi the United States, anda resident oit the city o'i' New York, Bronir'County, and @tate oi? NewYork, have invented certain new and useful Improvements in AutomobileCold-Air Dellectors, of which the following is a full, clear, and exactdescription. y

Among the principal objects which the present invention has `in vieware: to avoid. cooling the carburetor or gasoline distributing stationconnected therewith during the operation ot the engine; to promotevapori` Zation oi the gasoline by utilizing the heat oi the engine torwarming the carburetor and distributing station connected therewith; toutilize the heat oit the engine ot an automobile tor heating the body otthe automobile during weather requiring the same; to avoid the heatduring the warm season; and to simplify and cheapen the apparatus foraccomplishing the above-mentioned purposes.

Descrip tion.

As at present constructed, an automobile during the cold season, aswellas the warm, draws air by means oiL' al rapidly moving tan 7, through aradiator 8. The cold air thus drawn is only partially heated in itsrather short `passage through the radiator. This cold air is drivenbackward by the tan and by the motion of the car to impinge on themotor, 'arburetor and parts associated therewith, dash S) oi theautomobile and upon the tootboard 10 thereo'l. Moreover, drivers otautomobiles in excessively cold Weather' sulier particularly from coldfeet, due to the iiactthat thecold wind driven back by the tan 8 andinduced by the motion ot the automobile, passes the engine and partsthereof without being properly heated, and is usually delivered throughthe slots or critic s in which. the toot lever controls Ylior theautomobile extend. intensely cold air is thus precipitated upon the feetont the chauffeur.

` The present invention has for its object primarily to deflect the airtaken through the radiator S and moved by the Ytan 7, so as to deliverthe same below the crank case 11 oft the engine 12. p The current thusinduced would carry the cold air down over the mudguard with which thevautomobile is provided, and well below the tootboard 10 or the dash 9.This is accomplished in accordance with the present invention by forminga detlector 13, which may be secured in position as shown best in Figure1 of the drawings, at the rear ot the fan, to extend down in Front ot'the engineblock and wrap closely about the crank case 11, so as todeflect the air coming `through the radiator 8 towad the mud pan belowthe engine structure.

As shown best in'Figure 2 of the drawings, the de'tlector 13 is providedwith van opening 11i, through which in service .passes the return waterpipe 15 ot the circulatory system for the water jackets oit' the engine12. An opening 16 is made in the detiector 13 between the opening 14Cand the forward edge of the. said detlector. The opening is closed by alacing 17, when the deflector is adjustedto its active working position.A throat 18 is formed for straddling the crank case 11 and partsassociated therewith. The dellector is furnished with a number of shortends ot cord 19, by which the various edges oit the shield are held inoperative relation to the radiator and frame of the chassis. Arelatively long cord 20 is fastened at one end by a button 21 to the`shield and is adapted for engaging a second button 2Q at the` oppositeside of the throat 18. The cord 20 is in service passed down under thecrank case 11 and parts associated therewith and drawn taut to besecured to the button 22. This holds the rear of the shield firmly infan 7.

lWhen the various short ends 19 are secured to the packing string 2?)for the radiator and hood, and to convenient parts of or associatedwith.the sidebar Q4 ot the chassis, it will be found that the cold airthereafter drawn bythe ian 7 through the radiator 8 will be carried bythe detlector to below the crank case ot the engine, and into the spaceabove the mudguard with which the engine is provided.

This permits the heat of ,the engine to be utilized for `heating thebody of the car directly behind it, or that portion of the 'positiondirectly behind and in line with the car which is usually occupied bythe chauffeur. To this end the dashboard 9 and the footboard 1() areprovided with a series of perforations 25. he perforations 25 permit theheated air to rise into the space behind the. dashboard and above theViootboard which operates to provide warmth for the chauieur.

When the weather is warm enough to make it desirable to avoid heat, thecurtain 26 is drawn down over the perforations 25, and held in operatingposition by the hook 27. The detlector 13 is then removed from service.With the arrangement thus made the automobile and the chauliieursdriving station therefor is placed in the position previously enjoyed. i

In some instances, l provide small side curtains 28 which normally coverthe openings 29 formed in the detlector 13. Then desired these curtainsmay be rolled as shown on the left side of Figure 2 of the drawings andsecured in raised position by straps 30. The curtains are fastened inlower position by being secured by buttons 31. This expedient isemployed for modifying the efliect oit the deflector 13 as when duringthe day the weather modilies and it is desirable to permit some of thecooling air to travel back into the engine space for assisting incooling the engine and parts connected therewith.

iVhile the invention has been described as a device for promoting theheating of the car body and particularly of the portion thereof adjacentto the dashboard and tootboard, it will be understood that thedeflection of the cold air as indicated also protects the carbureter anda vacuum tank it the car be provided with one from the cooling effect ofthe air drawn in by the izan.

It is obvious that ir" the cool currents of air are deflected from theca-rbureter and gasoline distributing system connected therewith, theheat of the engine will materially assist in the operation of thecarburetor to modify advantageously the enect oi cold Weather thereon.

Y lhile l have herein described the deflector 13 as supported by thewater pipe 15A and as held in position by the cords 19 attached to theradiator 8, l may employ other means equally eli'ective` though lessdesirable, such as providing a spreading hoop or bowed frane on whichthe deiiector is stretched, said trame being disposed so that thededector stands immediately at the rear of the fan. ln this case lextend the 'fabric of the detiector to 'form a loose packing to engagethe engine hood when the same is lowered in service position therebypreventing the passage of air around the said hoop and detlector. rlfheto m shown in the drawings is, however, preferred as being simpler`cheaper of manufacture, and also as offering facility for storing awayin thc automobile as it may be closely lfolded to occupy very littlespace.
